The since-tainted funds went to three of New York’s current top officials: Gov. Cuomo, Attorney General Eric Schneiderman and Comptroller Thomas DiNapoli, as well as Mayor de Blasio, according to election filings.

The lion’s share of donations came from lobbyist Brian Meara, who testified that he set up a meeting between Silver and an executive at the Glenwood Management real-estate firm that helped the then-Assembly speaker score $700,000 in illegal kickbacks.

Those contributions, all made after Meara was outed as a cooperating witness, include $7,500 to the state Republican Senate Campaign Committee, $4,100 to Assemblyman Edward Braunstein (D-Queens) and $1,000 to the state Democratic Assembly Campaign Committee.

Meara gave Silver $1,000 in November 2014, just weeks before the Manhattan Democrat’s fall from grace.

Silver and Skelos, the former state Senate majority leader, were both convicted in influence-peddling schemes and are awaiting sentencing in federal court.

Government witness Anthony Bonomo — who took leave as chairman of the New York Racing Association following Skelos’ May arrest — has made 61 donations for a total of $265,000.

That money includes more than $66,000 give to Cuomo, $37,500 to DiNapoli and more than $25,000 to Schneiderman.

Bonomo, CEO of the Physicians’ Reciprocal Insurers firm, testified that he gave Skelos’ son, Adam, a no-show, $78,000 job following a “blizzard of requests” from the Long Island Republican to hire his kid.

Records show that Bonomo gave $6,100 in contributions to the elder Skelos. A third witness, lawyer Charles Dorego of Glenwood Management, donated $19,825 in 15 contributions.

But as Glenwood’s general counsel, Dorego had a hand in the $14 million that the corporation, its billionaire founder Leonard Litwin and its limited-liability companies have dispensed during the past decade.

City records also show all three men served as “bundlers” for candidates, with Bonomo rounding up $44,500 for Mayor de Blasio, to whom he has personally contributed $7,425.

The Post previously revealed that Dorego collected $149,900 for city Comptroller Scott Stringer.

Fellow lobbyist Michael McKeon insisted that Meara’s non-prosecution agreement didn’t grant him “any kind of immunity” and said he testified “because it was the right thing to do.”

Bonomo and Dorego did not return calls for comment.

“The governor’s decisions are not influenced by contributions, as testimony in the trials showed,” a Cuomo campaign spokesperson responded.
